Equipping modern production facilities with flexible process systems offers numerous advantages. For example, it is possible to react quickly to new market and product requirements, and the acquisition of only one system leads to immense space and cost reductions. However, it must be possible to guarantee automatic process adaptation or rapid replacement of mechanical components on the plant during daily operation.
Netzsch recognised this trend years ago and designed a modular system in the area of dry grinding with the Condux impact mill series, which can accommodate up to 4 rotor types by means of application-specific housing designs. In addition, the simple housing design makes the mill easier and faster to clean compared to conventional designs. Likewise, a repeatedly expressed customer wish has been met by a narrower gradation of the sizes in the smaller range. Equipped with different grinding tools and stators, a product-optimised mill is now available that can also be used in pressure-shock-resistant or inert-gas systems and in cryogenic grinding.
Another version of the proven Condux is now available with an integrated dynamic air classifier. This is used when the desired final fineness cannot be achieved with conventional sieve-less pin or blower mills with sieve insert. With the new Condux variant, a variable setting of the separation limit is easily achieved by adjusting the classifier wheel height. This results in an exact upper particle size limitation of the product during grinding in the range < 50 µm.
In contrast to conventional classifier mills, the grinding disc and classifier wheel are connected to each other in a rotationally fixed manner and are operated by a common drive motor. This considerably reduces the investment costs of the plant and enables economical ultra-fine grinding.
All in all, the Condux impact mill is the ideal, highly flexible solution for grinding many products from the industrial sectors of food, cellulose derivatives, animal feed, chemicals and plastics with particle sizes < 50 µm.
